Abstract
A process for the oligomerization of olefins which comprises contacting the olefin or olefin mixture with a catalyst consisting of trifluoromethanesulphonic acid monohydrate (CF3SO3H.H2O). The reaction may be carried out with or without solvents, at temperatures of from 20 to 180 DEG C. The thus obtained oligomers are then hydrogenated and used as bases for synthetic lubricants.
